differential

Question 2

Genomic imprinting is an example of epigenetics.
__________________

Accepted Answer

Genomic imprinting involves the epigenetic marking of specific genes in a parent-specific manner, leading to their differential expression in offspring depending on which parent they were inherited from. Therefore, it is considered an example of epigenetics.

Question 3

Eukaryotes have inducible genes that respond to environmental stimuli.
__________________

Accepted Answer

Eukaryotes have inducible genes that can be turned on or off in response to specific environmental signals or stimuli. This allows the organism to adapt to changes in its environment and respond to challenges such as nutrient availability, temperature, or stress. Examples of inducible genes in eukaryotes include those involved in the immune response, hormone signaling, and metabolic pathways.

Question 4

DNA methylation is a form of transcriptional regulation by eukaryotes.

Question 7

The leucine zipper has a unique structure compared to the other transcription factors because it is a dimer.
__________________

Accepted Answer

The leucine zipper is a type of transcription factor that forms a dimeric structure, in which two protein subunits are bound together through the leucine zipper domain. This structure allows the leucine zipper to bind to specific DNA sequences and regulate gene expression.

Accepted Answer

increases

Question 15

A repressor operon regulates the gene expression of anabolic pathways.
__________________

Accepted Answer

A repressor operon, such as the trp operon in bacteria, typically regulates anabolic pathways by inhibiting gene expression when the end product is abundant.
